Demystifying Metal-Cored Wires

Every welding power source, component and filler metal has its unique benefits, as well as certain limitations. Metal-cored wires are no different. While certainly not a new technology, metal-cored wires have been gaining popularity in recent years, particularly in the manufacturing, fabricating and repair industries. Still, there seems to be some mystery surrounding this filler metal, with much less known about it among the general public compared to its counterparts, including solid wires. In many cases, there are some common misconceptions surrounding metal-cored wires, too.

To gain a better understanding of metal-cored wires, it helps to consider the technology behind these filler metals and the applications for which they are best suited. Additionally, it is important to know the general characteristics of metal-cored wires, along with the ways they can bring potential improvements in the welding operation.

Know the Basics to Get the Best Results from Metal-Cored Wire

When used with the right applications, metal-cored wire can help minimize costs, improve quality and increase productivity in the welding operation. Like any filler metal, metal-cored wire has unique characteristics, benefits, limitations and applications where the wire is best suited. Knowing when and how to use this wire can help companies achieve the best success with the product.

This article discusses the most appropriate applications for metal-cored wire, some of the characteristics to consider when choosing this filler metal and tips for welding successfully with metal-cored wire.

Reduce Moisture-Absorption and Cracking Risks With Seamless Wires

Reducing the opportunity for moisture pickup — in the filler metal and deposited weld metal — is important in any welding operation, but especially in industries with more critical applications.

Controlling moisture helps minimize the risk of hydrogen-induced cracking in these demanding, high-strength applications, and with it costly repairs or potentially catastrophic weld failures.

Seamless wires can help in moisture-control efforts. These filler metals also offer excellent impact toughness, even at lower temperatures, and low hydrogen properties to further mitigate cracking risks.
